Comment 3 Vivia Nikolaidou 2017-10-13 11:19:13 UTC 
This returns an empty string. It is correct (!)

It's not returning a serial number, despite the misleading API call. It is returning a user-supplied label. The user can launch the vendor-supplied utility and give the card a label through that utility, and then this label will be returned with this API call. If the user hasn't supplied a label yet, it will return an empty string.

This is still useful for our use case, but it's still pending a proper test - we haven't yet supplied a label to see if we'll get it back, and we also haven't tested to see how persistent it is (does it survive reboots? does it survive moving the card to another computer?)
